About AI Training Work

AI training (also called data labeling or human feedback work) is the human side of building modern AI: people prepare and review examples that teach models how to write, code, translate, and make decisions.

This role focuses on evaluating and testing a developer-facing AI coding tool — your feedback directly helps make the tool more accurate and useful for engineers.

The Role

We are hiring intermediate full‑stack or back‑end Python engineers to test an internal coding tool for a deep‑tech AI research lab backed by $10M from top VCs including NEA and General Catalyst.

The team includes professors, serial entrepreneurs, and researchers from Stanford, Harvard, Google Gemini, and Microsoft Research. This is a contractor, part‑time opportunity available worldwide.

• Work type: Contractor / Part‑time
• Location: Remote — worldwide
• Time commitment: Less than 20 hours per week
• Labeling software: Internal proprietary tooling
• Label types: Computer programming (coding) and evaluation/rating

What You'll Do

Your primary responsibility is to test the client's internal coding tool and evaluate its outputs against real engineering tasks.

• Execute coding tasks and interact with the internal tool to produce or review code samples.
• Evaluate and rate tool outputs for correctness, style, and usefulness using the proprietary interface.
• Report bugs, usability issues, and suggestions that improve developer workflows.
• Follow provided instructions to log results and complete evaluation tasks within the internal tooling.

Requirements

Candidates must meet the technical and commitment requirements below.

• Intermediate experience level as a Python engineer (full‑stack or back‑end).
• Hands‑on experience with AI coding tools such as Cursor, Windsurf, and Claude Code.
• Comfort evaluating code outputs and providing clear, structured feedback.
• Ability to work remotely and independently within a part‑time, contract arrangement.
• Willingness to use internal proprietary tooling to perform and submit evaluations.

Who Should Apply

This role is a fit if you are an intermediate Python developer who enjoys testing developer tools and shaping AI that writes code.

• Full‑stack or back‑end Python engineers with practical coding experience.
• Engineers who have used AI coding assistants and can critically evaluate generated code.
• People seeking flexible, remote, part‑time contract work under 20 hours/week.

Pay & Time Commitment

Compensation is USD $100 per hour on a pay‑per‑hour basis. The role is part‑time and capped at less than 20 hours per week.

Employment type is contractor; you will use the client's internal proprietary tooling to complete evaluation tasks and submit results.

How to Apply

Apply through the OpenTrain listing for this role. Creating an OpenTrain account is free and applications typically take only a few minutes.

If your profile matches the requirements, the client will reach out with next steps and access instructions for their internal tooling.
